摘要

以吡啶氨基和膦配体为保护剂，合成了一种金色富勒烯，其组成为 [Au42(Ph3P)10(5-CF3-Hpa)8] (CF3COO)2（5-CF3-H2pa = 5-三氟吡啶-2-胺）（Au42）。单晶 X 射线结构分析表明，该簇具有 D3h Au4210+ 核心，可描述为中心核壳结构 Au@Au15@Au26。Au15@Au26 核壳中的 41 个金原子可以通过在 C78（D3h）的每个多边形中心放置一个金原子而得到。令人惊讶的是，这个贵族簇的中心金原子具有金属纳米簇中最高的配位数 15。量子化学研究表明，Au42 的优异稳定性源于 Au42 内核的超原子特性和金与配体的相互作用。

Ligand-Protected Golden Fullerene Au42 with Unprecedented Metal Coordination Number of 15

A golden fullerene with a composition of [Au42(Ph3P)10(5-CF3-Hpa)8] (CF3COO)2 (5-CF3-H2pa = 5-trifluoropyridyl-2-amine) ( Au42 ) has been synthesized with pyridylamino and phosphine ligands as the protecting agents. Single crystal X-ray structural analysis reveals that the cluster has a D3h Au4210+ core, which can be depicted as a centered core-shell structure Au@Au15@Au26. The 41 Au atoms of the Au15@Au26 core-shell can be derived from placing a gold atom in the center of each polygon of C78 (D3h). Surprisingly, the centered gold atom of this noble cluster has the highest coordination number in metal nanoclusters of 15. Quantum-chemical studies suggest that the excellent stability of Au42 results from both the superatomic characteristics of the Au42 kernel and the gold-ligand interactions.
